Application filed December 10, 1923, Serial No- 679,636. Renewed June 19, 1925.

To aZZ 'whom it may concert.:

Be it known that I, CARMEL O. BLANCO, subject to the King of Italy, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Choke Controls, of which the following is a specification.

This invention relates to new and uscful improvements in choke control.

One object of this invention is to provide a means for choking or rendering the mixture going from the carburetter to the cylinders of the engine richer, and to maintain this rich mixture until the engine is warmed up or so long as it may be necessary.

VVith the above and other objections in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying draw ings, wherein Figure 1 is a side elevation of a Ford engine with my device attached to the dash of the body of the car, and with suitable rods running therefrom to the carburetter and instrument board of the car.

Figure 2 is a side elevation of the device and,

Figure 3 is an edge view thereof.

Referring now more particularly to the drawings wherein like numerals of reference refer to similar features of the device in each fignre, the numeral refers to the outwardly turned end lug of the bracket 5. The lug 4; has radiating corrugations as 6 preferably arranged in a circular row. This bracket 5 is provided with holes 7, 7. Bolts 6 pass through these holes and through the'dash 9 of the car and are held in fixed position by means of the nuts 10. A fluted disc 11 having` the arms 12 and 13 is adapted to lie against and cooperate with the fluted side of the lug 4, and the bolt 14 passes through these central bearings in these two elements, and also passes through the s ider 15, and the lock washer 16, all of whicli are held operatively together by means of the nut 17. The spider 15 has radiating flexible fingers which rest against the lug 4, causing the central part of the spider to bear yieldingly against the washer 16 to lock the nut 17 against detachment.

To the shorter arm 12 a rod 18 is attached and passes through both the dash 9 and the instrument board 19, while the rod 20 is attached at one end to the arm 13, and at the other end to the arm 21 of the butterfly Valve in the carburetter 22.

When the engine is cold a pull upon the rod 18 Will raise arms 12 and 13 and through them rod 20 and arm 21 thus causing the butterfly valve to cut off a portion of the cold air passing through the carburetter and thus give a richer mixture to the engine.

A device of this Character is cheaply made, very effective in actual operation and is easily installed on the present type of Ford cars.

What I claim is A device of the character described including a bracket having one end upturned forming a lug, said lug being provided with radiating corrugations, means for sec'uring said bracket to the dash of an automobile, a

Abell crank formed of a fiuted disc and two radiating arms, said disc fitting againstl the corrugated side of said lug, a. spider having flexible fingers fitted against the other side of said lug, a bolt passing through said disc, lug and spider, a securing` nut threaded onto said bolt and resting against said spider, a rod extending through the instrument board, and dash of the vehicle and attach-ed to the free end of one of said arms, and another rod connected at one end to the free end of the other arm, and at its other end connected with the air inlet valve of the vehicle carburetter.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CARMEL O. BLANCO.
